Found in coral-rich seaweed reefs in the Pacific Ocean, clown triggerfish, such as this patterned juvenile in Indonesia's Tukangbesi Islands, are master predators. The fish blow streams of water at the sand to expose hiding prey, then use their powerful jaws and rows of sharp teeth to crush through hard-shelled reef creatures such as sea urchins, clams, snails, and crabs.
